WebAbstract. The purposes of this study were to examine the relationships between dynamic strength index (DSI) and other strength-power performance characteristics and to contextualize DSI scores using case study comparisons. 88 male and 67 female NCAA division I collegiate athletes performed countermovement jumps (CMJ) and isometric mid … WebAbstract. Read online. UR50 ultra-early-strength cement-based self-compacting high-strength material is a special cement-based material. Compared with traditional high-strength concrete, its ultra-high strength, ultra-high toughness, ultra-impact resistance, and ultra-high durability have received great attention in the field of protection engineering, …
Dynamic Strength Training: 13 Exercises To Build …
WebReactive strength index (RSI) is the ratio between the height jumped and the ground contact time, calculated by dividing the jump height by the ground contact time. The jump height time is the time between the participant's feet leaving the timing mat or force platform and when they contacted it again. The vertical jump height in meters can be ... WebDec 19, 2024 · The primary aim of this investigation was to determine the effects of a four-week period of in-season strength training on the dynamic strength index (DSI).
